Microcystic adnexal carcinoma simulating scarring alopecia

The microcystic adnexal carcinoma is a rare, locally aggressive malignant adnexal neoplasm associated with signifi cant morbidity. It is often underdiagnosed due to clinical and histopathological resemblance with other cutaneous neoplasms and / or a combination of lack of familiarity associated with inadequate samples. We report a case with clinical hypothesis of scarring alopecia and histopathological diagnosis of microcystic adnexal carcinoma with favorable outcome in a follow-up of eleven years, after surgical treatment.
